Abstract
Background and Aims:
Both obesity and life expectancy are increasing worldwide. The present study aimed to report the outcomes of bariatric surgery in patients who are older than 65 years of age.

Methods:
A retrospective review of prospectively collected data from patients aged over 65 years who underwent LRYGP and LSG in our institute from 2006 to 2016. The data analyzed included age, preoperative and postoperative weight, body mass index, postoperative complications, and co-morbidities.

Results:
A total of 47 patients over 65 years (66.5 ± 0.2 years) underwent bariatric surgery in our institute. Of these 47 patients, 21 patients (44.68%) had undergone LRYGP, 20 patients (42.55%) LSG, and six patients (12.76%) conversion of the gastric band (5 patients) and Maison (one patient) to LRYGP. The mean preoperative weight and body mass index were 109.06 ± 2.33kg and 40.93±0.74 kg/m2, respectively. The median length of follow-up was 12 months (range 1–48). The overall complication rate was 23.4%. No mortality occurred. For 21 patients, the mean percentage of excess weight loss and body mass index was 77.5± 6 % and 29.7±1 at 12 months. The resolution of diabetes mellitus, hypertension, and Obstructive sleep apnea syndrome was 70%, 57%, 75%, and 100 %, respectively.

Conclusions:
Bariatric surgery in carefully screened patients ±65years can be performed safely and improve co-morbidities.
